Get a pointer to the data contained in the surface, and deny GPU access to the surface.
Type: DXGI_MAPPED_RECT*
A pointer to the surface data (see DXGI_MAPPED_RECT).
Type: UINT
CPU read-write flags. These flags can be combined with a logical OR.
- DXGI_MAP_READ - Allow CPU read access.
- DXGI_MAP_WRITE - Allow CPU write access.
- DXGI_MAP_DISCARD - Discard the previous contents of a resource when it is mapped.
Type: HRESULT
Returns S_OK if successful; otherwise, returns one of the error codes that are described in the DXGI_ERROR topic.
Use IDXGISurface::Map to access a surface from the CPU. To release a mapped surface (and allow GPU access) call IDXGISurface::Unmap.
